What does it mean? We don't know, but we want to see more of it!
It looks like things are pretty cheery at Maurico Pochettino's Tottenham Hotspur this season. First off, they managed to keep hold of Harry Kane, regardless of which team the back pages had linked him with. And secondly, they've got a load of very talented, and very exciting youngsters in their ranks.
Of course there's Kane, but then there's Eric Dier, Ryan Mason, Nabil Bentaleb, Ben Davies, Heung Min-Son and the very in-form, Dele Alli.
Though Son has only scored once in the Premier League for Spurs, he still looks to be having a pretty good time. Alli, on the other hand, has had an incredible start to his first season in England's top-flight and has already made his England debut.
With Spurs now just four points off the top of the table, it seems like there are going to pretty drastic measures to ensure that no one figures out their tactics.
As Alli and Son proved last night in their 1-0 win over Azerbaijani side Qarabag FK, with this really bizarre secret handshake:
Any idea what it means? All we know is that we've not seen a secret handshake that cool since the Fresh Prince and DJ Jazzy Jeff got together.
